gpiolib: acpi: Improve struct acpi_gpio_info memory footprint

The struct acpi_gpio_info has two boolean members that are located
not close to each other making two gaps due to alignment requirements.
Group them to improve memory footprint.

`pahole` difference before and after (on 32-bit):

-       /* size: 36, cachelines: 1, members: 9 */
-       /* sum members: 30, holes: 2, sum holes: 6 */

+       /* size: 32, cachelines: 1, members: 9 */
+       /* sum members: 30, holes: 1, sum holes: 2 */
